ION BEAM TREATMENT METHOD FOR PRODUCING SUPERHYDROPHILIC GLASS MATERIALS

摘要

Process for treatment by an ion beam of a glass material where:
the acceleration voltage of the ions is between 5 kV and 1000 kV;the temperature of the glass material is less than or equal to the glass transition temperature;the dose of nitrogen (N) or oxygen (O) ions per unit of surface area is chosen within a range of between 1012 ions/cm2 and 1018 ions/cm2 so as to reduce the contact angle of a drop of water below 20°;a prior pretreatment is carried out with argon (Ar), krypton (Kr) or xenon (Xe) ions in order to stengthen the durability of the superhydrophilic treatment.;Superhydrophilic glass materials of long duration are thus advantageously obtained.

1. A treatment process for enhancing the hydrophilic properties of a glass material, wherein it consists of an ion bombardment where:
the ions of the ion beam are selected from the ions of the elements of the list consisting of nitrogen (N) and oxygen (O); - the acceleration voltage, AV, of the ions is greater than or equal to 5 kV and less than or equal to 1000 kV , in particular greater than or equal to 5 kV and less than or equal to 200 kV, indeed even greater than or equal to 10 kV and less than or equal to 100 kV; the temperature of the glass material is less than or equal to the glass transition temperature; the dose of ions per unit of surface area is located within a range of between 1012 ions/cm2 and 1018 ions/cm2, in particular of greater than or equal to 1015 ions/cm2, indeed even of greater than or equal to 1015 ions/cm2 and less than or equal to 1017 ions/cm2.
